Beitnknown that ll, SAMUEL G. Fosrnn, a citizen-otl ythe United States,residing at lilestield, in the county of Union and State have inventedcertain new and useful Improvements in adjustable Window-Screens; and ldo declare the fol- A, lowing to be -a`full, clear, and exactdescription of the invention, such as will enable it rippen tains tomalte and use the same. I

rilhis invention relates to improvements in adjustable window screensand more particularly to an :improvement over the construction disclosedin United States Patent .1,022,312 of April 2nd, 1912. In the patentedydevice a screen frame was provided consisting of four rectangularsections telescopically` engaged with` cach oth r, a sheet 2O otwovenwire having` diagonal strands, was

received at its edges in channels oit' said `trame sections, and rivetswere employed at spaced points for securing;- the screen to the irame.in actual practice, these rivets have 2.5 been foundto z( :reatly injurethe wire mesh and to also interfere with smooth adjustment ot the screento dil'erent and shapes. rihe principal object iny invention thereforeis to devise a novel construco'tion for anchoringl the screen wire tothe sectional frame, without the use of any rivets o1I like fasteners,the arrangement being' such that the sheet ot wire mesh is connectedwith the frame substantially throughout its perimeter.

The patent above vdiscussed included a pair ot' crossed brace bars whichwere pivoted together at their crossing point and also pivoted to thecorners of the angular trame This construction has not proven entirelysatisfactory and a further aim therefore is to provide an improvedconstruction for retaining the brace bars in proper relation with thecorners of the frame, without the necessity of employing any pivots.

lVith the foregoing` and minor objects in view, the invention resides inthe novel construction andarrangement of 'parts herein after describedand claimed, the descriptive matter beingr supplemented by theaccompanying drawings.

showing the same extended horizontally.

ing the manner in which the screen may 'he iff extended vertically. i

llig. i is an enlarged horizontal sectif'inal view as indicated 'by lineof Fig. 2. j

5 is a view similar to l*`ig.4, a'sindicated by line ot Fig. $3. v 'f fln' the' drawings above brietiy described Y 7 the numerals l designatetour right angular frame sections whose arms are telesu'ipical'lviconnected to provide a complete rectangular traine 'which may beaiiljusted both vertiially and horizontally. Each jframe section 'is ofsubstantially rectangular toi-m inv transverse section as shown in Figs.i and :3, one side thereo'tx however, being longitudinally split asshown at 2, providingl a relatively wide side iiang'e 3 and a narrowerflange l'spaced outwardly therefrom to a slight' extent.

The sheet of screen w're passes' betweenf..

the flanges 5l and e through the split'or slot 2 and the edges of saidsheet are abruptly bent as shown at 6 so as to hook around the flanges3, thereby connecting the screen wire with the trame sections l,throughout the perimeter of the former. This provides a much .moreeffective anchorage than the rivets disclosed in the patent abovereferred to and insures much easier operation.

it the tour corners of the screen, the diagonal strands 7, which strandsare free of attachment to each other, are cut oit as indicated at 8,providing for the necessary moveinentof said justed. ln some positionsotthis frame, the cut away corners of the screen wire might forni openingsallowing flies and other insects to enter, but in order to prevent this,ll provide four right angular corner clips 9 having parallel sidelianges l0 between 'which the corners of the trame sections are solderedor otherwise secured. The tianges lOeXtend inwardly from the innercorners of the frame sections, suiiicientlyto close any openings whichmight be formed in the manner above set forth and it will be seen thatthe cl'fps 9 also serve to trame sehtions. Furthermore, these clips act'to retain the ends ot' crossed brace bars l1, in the inner corners ot'the trame sections l, making it 'unnecessary to use pivots such as thosedisclosed in the patent above discussed. Une pivot ll however isemployed at the y point where the barsfll cross each other.

substantially eiectively brace the' ing diagonal strands By employingthe features of construction shown and described, a much more desirableand practicalscreen is provided, than that disclosed by Patent 1,022,312and this screen may be `extended either vertically ororizont'ally-without any binding of the frame sections or tearing of thewire.

Since excellent results are obtainable from the details disclosed, suchdetails are preferably followed, but within the scope of the inventionas claimed, numerous minor changes may be made.

I claim:

1. An adjustable window screen comprising a frame formed of adjustablyconnected sections having longitudinal channels jointly extending aroundthe entire trame, and a sheet ot woven. wire having diagonal strandstree of attachment to eachotl1er, the edges of said sheet being abruptlybentinto sai channels and hooked over one 'side thereof in slidingengagement therewith.

2. n adjustable window screen compris ing a frame Jformed ot' adjustablyconnected sections` said frame sections being hollow and havinglongitudinal slots at one side of the frame, and a sheet of woven wirehavfree of attachment to each ot 1er, the edges of -said sheet beingabruptly bent through said slots and hooked slidably around the portionsof the framey y sections at one side ot' said slots.

window screen comprising a frame formed ot' `adjustably connected framesections, each frame section being hollow and of substantiallyrectangular form in transverse section 3. An adjustable with onesidelongitudinally7 split to forni relatively wide e and narrow sideflanges, the latter being outwardly offset from the former, and a sheetof woven wire having diagonal strands free of attachment to each other.the edges of said sheetbeing abruptly turned into the above mentionedsplit ot' each frame section and hooked slidably around the rela-tivelywide ange thereof. A

4. An adjustable window screen comprising four right angular framesections slidably engaged with each other to form a rectangular i' aune,a sheet ot' woven wire connected at its edges with said frame and havingdiagonal strands free of attachment to each other, nonextensible crossedbraces pivoted together and having their ends located in the innercorners ot' said trame sections, and braces for the corners of saidtrame sections serving to retain said b `ace ends in said corners.

An adjustable window screen comprising tour right angular frame sectionsslidably engaged with each other to form a rectangular frame, a sheet ofwoven wire connected at its edges with said frame and having diagonalstrands tree ot' attachment to each other, non-extensible crossed bracespvoted together and having their ends located in the inner corners ofsaid frame sections, and corner clips secured on the corners of saidframe sections and having side flanges retaining said brace ends in saidcorners.

In testimony whereof l have hereunto set my hand.

SAMUEL G. FGSTER.
